Goodness.
You'd think it was the end of the world.
Really, should you find yourself overly concerned or irritated by such jokes, ask yourself why it irritates you. Do you feel that the jokester is ridiculing you personally? And if so, why do you value the opinion of someone who would find a joke like that amusing?
Seriously; who cares? Let them make their jokes. They don't define you so much as they define the person making them. If you feel they
do define you, you should take a long step back and ask yourself why you let others decide who you are.
I, too, was born and raised in WV, and have heard the same jokes you have. However, I also know who I am, and the WV jokery affects me not in the slightest.
Of course, I also despise Pete Rose, and anything he says that knocks him down a few notches in the opinion of his fanbase is thumbs-up with me.
